Proprietary Tethers

Nonfree (proprietary) software is very often malware (designed to
mistreat the user). Nonfree software is controlled by its developers,
which puts them in a position of power over the users; that is the
basic injustice. The developers often exercise that power to the
detriment of the users they ought to serve.

Tethering a product or program to a specific server is an injustice
in itself. This page reports instances where tethering was used to
harm the users directly.

The owners suspect this is to pressure them to buy a newer model. If
they are wise, they will learn, rather, to distrust any product that
requires users to talk with them through some specialized service.
